Definitions

  • the present disclosure relates to a laundry treating apparatus, and more particularly, to a laundry treating apparatus including a driving unit directly connected to a drum configured to accommodate laundry so as to rotate the drum.
  • laundry treating apparatuses are apparatuses configured to remove dust and foreign substances from laundry by applying physical force thereto, and include washers, dryers, clothes refreshers (i.e., clothes stylers), etc.
  • the washers are configured to perform a washing cycle in which foreign substances may be separated and removed from laundry by supplying water and detergent.
  • the dryers are classified into an exhaust-type dryer and a circulation-type dryer, and both dryers are configured in common to perform a drying cycle in which moisture is removed from laundry by producing hot air having a high temperature through a heater and exposing the laundry to the hot air.
  • a dryer may be configured to intensively perform the drying cycle by omitting components configured to supply water to laundry or to drain water and omitting a tub provided in a cabinet to receive water.
  • the inner structure of the dryer may be simplified, and drying efficiency may be improved by directly supplying hot air to the drum configured to accommodate the laundry.
  • Such a dryer may include a drum configured to accommodate laundry, a hot air supplier configured to supply hot air to the drum, and a driving unit configured to rotate the drum.
  • the dryer may dry the laundry accommodated in the drum by supplying hot air to the inside of the drum, and may uniformly expose the surface of the laundry to hot air by rotating the drum. Consequently, drying of the laundry may be completed through uniform contact of the overall surface of the laundry with hot air.
  • the driving unit In order to rotate the drum, the driving unit needs to be fixed to the inside of the cabinet. Further, when the driving unit is provided to rotate a rotating shaft coupled to the drum, the driving unit needs to be provided parallel to the rotating shaft.
  • the dryer does not include a tub fixed to the inside of the cabinet, and thus has a difficulty in fixing the driving unit to the tub in the same manner as the washer.
  • FIG. 1 shows the structure of a conventional dryer configured such that a driving unit is fixed to the rear surface of a cabinet.
  • the above dryer may include a cabinet 1 configured to form the external appearance of the dryer, a drum 2 rotatably provided within the cabinet 1 so as to accommodate laundry, and a driving unit 3 provided so as to rotate the drum 2.
  • the driving unit 2 may be disposed on the rear surface of the drum 2 so as to rotate the drum 2, and may be fixedly coupled to a rear panel 11 forming the rear surface of the cabinet 1. Therefore, the driving unit 3 may be fixed to the cabinet 1, and may thus rotate the drum 2.
  • the driving units 3 of the above-described conventional dryers may include in common a stator 31 fixed to the rear panel 11, a rotor 32 rotated by the stator 31, and a rotating shaft 33 coupled to the rotor 32 so as to rotate the drum 2, and may further include a reducer 37 provided to increase torque while reducing the RPM of the rotating shaft 33 so as to rotate the drum 2.
  • the conventional dryers may further include in common a fixing unit 4 configured to fix the driving unit 3 to the rear panel 11.
  • the fixing unit 4 may include at least one of a first fixing member 41 configured to fix the stator 31 to the rear panel 111, and a second fixing member 42 configured to fix the rotating shaft 33 to the rear panel 11. Therefore, in the conventional dryers, the driving unit 3 is disposed parallel to the rotating shaft 33 coupled to the drum 2, and may thus stably rotate the drum 2.
  • the rear panel 11 of the cabinet 1 is provided as a thin steel plate, and is thus easily deformed or vibrated even by a considerably small external force. Further, the rear panel 11 receives not only the load of the driving unit 3 but also the load of the drum 2 through the rotating shaft 33, and maintaining the shape of the rear panel 11 may thus be difficult.
  • the rotating shaft 33 configured to connect the driving unit 3 to the drum 2 may be distorted. Accordingly, the driving unit 3 may generate unnecessary vibration or noise and, in severe cases, the rotating shaft 33 may be damaged. Further, bending or deformation of the rear panel 11 may generate unnecessary noise.
  • the distance between the rotor 32 and the stator 31 is temporarily varied, and may thus cause collision between the rotor 32 and the stator 31 or generate unnecessary vibration and noise.
  • the driving unit 3 further includes the reducer 37
  • the rotating shaft 33 coupled to the reducer 37 and a reduction shaft 33a configured to connect the reducer 37 to the drum 2 are separated from each other.
  • the reducer 37 is supported by the rear panel 11 through the stator 31 or the rotating shaft 33, when the rear panel 11 is deformed even slightly, the reduction shaft 33a and the rotating shaft 33 may be distorted or misaligned with each other.
  • the reduction shaft 33a connected to the drum 2 has a less position change than the rotating shaft 33 coupled to the driving unit 3 due to the load of the drum 2. Therefore, when the rear panel 11 is temporarily bent or deformed, the tilting degrees of the rotating shaft 33 and the reduction shaft 33a are different, and thus, the rotating shaft 33 and the reduction shaft 33a are misaligned with each other.
  • Such a conventional dryer does not suggest a flow path in which air of the drum flows in the base located below the drum, or an explicit implication or structure as to how to treat water condensed in the flow path. Therefore, the conventional dryer does not provide an implication as to how to change the structure of the base when the position of the driving unit 3 is changed.
  • Another conventional dryer which is on the market is configured such that a driving unit 3 is fixed to the bottom surface of a cabinet 1 (refer to Korean Patent Unexamined Publication No. 10-2019-0121656).
  • FIGS. 2(a) and 2(b) show the dryer in which the driving unit 3 is fixed to the bottom surface of the cabinet 1 or a base 5.
  • the bottom surface of the cabinet 1 may not be deformed or tilted.
  • the driving unit 3 may include a motor 34 fixed to the bottom surface of the cabinet 1, a rotating shaft 37 rotated by the motor 34, a pulley 35 rotated by the rotating shaft 37, and a belt 36 provided to connect the outer circumferential surface of the drum 2 to the outer circumferential surface of the pulley 35.
  • the dryer has problems that the rotational acceleration of the motor 34 should be limited to a designated level or less, and the motor 34 should be slowly accelerated or decelerated so as to prevent slip of the belt 36 when the drum 2 is rotated.
  • the conventional dryer may not rapidly change the rotating direction of the drum 2, thus being incapable of controlling rotation of the drum 2 or changing the rotating direction of the drum 2. Thereby, the dryer cannot control the rotating direction and the rotational velocity of the drum 2 during the drying cycle, and thus cannot maximally increase drying efficiency.
  • the compressor installation part 58 may be installed as close to the circulation flow path part 51 as possible so as to reduce heat loss of a refrigerant.
  • the water collection part 57 needs to be installed as close to the circulation flow path part 51 as possible so as to accommodate the condensed water.
  • the compressor installation part 58 and the water collection part 57 need to be installed so as to avoid the motor installation part 59, and need to be installed in a region of the base 5 other than the circulation flow path part 51 and the motor installation part 59.
  • the compressor 61 should also occupy a considerable volume, and thus, the compressor installation part 58 and the water collection part 57 may not be disposed in the extending direction (for example, in the forward and rearward directions) of the circulation flow path part 51.
  • a dryer provided with a heat pump configured to circulate air in a drum so as to dry laundry accommodated in the drum
  • a circulation flow path configured to circulate air therethrough is formed on one side of a base of a laundry treating apparatus provided with a heat pump, and an evaporator and a condenser are disposed on the circulation flow path in the forward and rearward directions.
  • a fan configured to generate air flow in the circulation flow path is provided behind the condenser. The condenser serves to heat air, and may thus be maintained at a high temperature during the drying cycle.
  • the distance between the evaporator and the condenser is not sufficiently secured. That is, the distance between the evaporator and the condenser is less than the distance between the condenser and the fan.
  • condensed water generated by the evaporator is not collected, and may be evaporated again by the condenser located adjacent to the evaporator.
  • heat loss of the condenser may be caused, and wet steam may be generated again and thus supplied to the drum, thereby reducing drying efficiency
  • a dryer having a steam injection apparatus configured to generate steam and inject the generated steam into a drum so as to remove contaminants from laundry and sterilize the laundry
  • a drawer having a water accommodator provided therein is installed at the upper portion of the front surface of the dryer, water accommodated in the water accommodator is transferred to the steam injection apparatus, i.e., a steam generator, provided at the rear portion of the dryer by a pump, and steam generated by the steam generator is injected into the rear region of the drum through a nozzle or the like.
  • a separate element such as the pump, is required to transfer water necessary to generate steam, and a flow path configured to connect the water accommodator to the steam generator located at the rear portion of the dryer needs to have a designated length or more. Therefore, water stagnant in the flow path may cause freezing of the flow path in winter time, and the stagnant water may be contaminated and thus generate odor.
  • dryers which have a separate steam generator and generate steam using condensed water generated during drying of laundry or water supplied from an external water supply sources, have been recently developed, thereby diversifying and improving laundry treating performance.
  • a water supply unit configured to receive water transmitted from an external water supply source so as to supply steam is generally located at the upper portion of the rear surface of the dryer for user convenience.
  • the above-described conventional dryer and a general drum washer are disposed in the vertical direction, and thus, efficiency of the installation space for the dryer and the washer is improved. That is, the washer having a relatively large weight is disposed on the ground, the dryer having a smaller weight than the washer is disposed on the washer, and thereby, utilization of the space in which the washer and the dryer are installed and use convenience may be increased.
  • the water supply unit provided on the upper portion of the rear surface of the dryer is located at a higher position from the ground, and may thus provide inconvenience of a worker or a user who connects the water supply unit to the external water supply source.
  • the distance between the water supply unit of the dryer and the external water supply source is increased, and thus, the length of a water supply hose configured to connect the water supply unit to the external water supply source may be unnecessarily increased.
  • the present disclosure has been made in view of the above problems, and an object of the present disclosure is to provide a laundry treating apparatus which includes a driving unit configured to reduce the rotational velocity of a rotor and then to transmit the reduced rotational velocity to a drum, and allowing the center of rotation of the rotor and the center of rotation of the drum to form a concentric axis.
  • Another object of the present disclosure is to provide a laundry treating apparatus which may secure a space between an evaporator and a condenser so as to prevent condensed water generated by the evaporator from scattering in the condenser.
  • Another object of the present disclosure is to provide a laundry treating apparatus which may secure a space between a condenser and a circulation fan so as to facilitate smooth generation of air flow in a flow path by the circulation fan.
  • Another object of the present disclosure is to provide a laundry treating apparatus which may increase the circulation rate of air in a flow path.
  • Another object of the present disclosure is to provide a laundry treating apparatus in which a steam generator configured to generate steam injected into a drum may be installed on a base.
  • Another object of the present disclosure is to provide a laundry treating apparatus which may supply steam generated by a steam generator to the front portion of a drum.
  • Another object of the present disclosure is to provide a laundry treating apparatus which may shorten the length of a flow path configured to supply water to a steam generator by disposing a water supply unit configured to store water necessary to generate steam and the steam generator adjacent to each other.
  • Another object of the present disclosure is to provide a laundry treating apparatus which may install a steam generator on a base so as to increase efficiency in space utilization.
  • Another object of the present disclosure is to provide a laundry treating apparatus and a method for controlling the same which may improve a water supply structure configured to generate steam so as to simplify a steam water supply flow path.
  • Another object of the present disclosure is to provide a laundry treating apparatus and a method for controlling the same which may improve a water supply position for steam generation when the laundry treating apparatus is stacked on another laundry treating apparatus, so as to provide convenience to a worker or a user.
  • Another object of the present disclosure is to provide a laundry treating apparatus and a method for controlling the same which may improve a water supply position for steam generation when the laundry treating apparatus is stacked on another laundry treating apparatus, so as to prevent a water supply hose configured to connect a water supply unit to an external water supply source from unnecessarily extending.
  • a laundry treating apparatus is provided such that a distance between an evaporator and a condenser is greater than a distance between the condenser and a circulation flow path fan.
  • a diameter of the circulation flow path fan may be greater than a height of the condenser.
  • the laundry treating apparatus may include a steam generator provided to supply steam to a drum, and a base may include a steam generator installation part in which the steam generator is mounted.
  • the steam generator installation part may be provided adjacent to the front portion rather than the rear portion of the base, and the steam generator may also be provided adjacent to the front portion rather than the rear portion of the base.
  • the steam generator may include a steam nozzle configured to inject the steam, and the steam nozzle may be disposed in front of the drum so as to inject the steam into the front portion of the drum.
  • the water collection part may be disposed to overlap the first heat exchanger in leftward and rightward directions.
  • the base may further include a collection guide part recessed from a portion of a bottom surface of the circulation flow path part facing the first heat exchanger so as to guide the condensed water to the water collection part
